To provide a failure detection device capable of detecting a failure of a sound generation device even when no sound is output.SOLUTION: A failure detection device 30 for detecting a failure of a sound generation device 10 for outputting sound on the basis of sound data from a speaker includes: digital watermark signal generating means 23 for generating a digital watermark signal, including verification data used for verification of whether or not the sound is output from the speaker; the speaker 11 for outputting the digital watermark signal as a sound; a microphone 12 for collecting the sound output by the speaker; collation data detection means 40 for detecting the collation data from the electronic watermark signal included in the sound collected by the microphone; and failure determination means 36 for determining whether or not there is a failure in the sound generation device by collating the collation data detected by the collation data detection means with the collation data that is included in digital watermark signal by the digital watermark signal generation means.SELECTED DRAWING: Figure 1

    【課題】音が出力されない状態でも音発生装置の故障を検出できる故障検出装置を提供すること。【解決手段】音データに基づく音をスピーカから出力させる音発生装置10の故障を検出する故障検出装置30であって、前記スピーカから出力されたか否かの照合に使用される照合用データを含む電子透かし信号を生成する電子透かし信号生成手段23と、前記電子透かし信号を音として出力する前記スピーカ11と、前記スピーカが出力した音を集音するマイク12と、前記マイクが集音した音に含まれる前記電子透かし信号から前記照合用データを検出する照合用データ検出手段40と、前記照合用データ検出手段が検出した前記照合用データを、前記電子透かし信号生成手段が電子透かし信号に含めた前記照合用データと照合して、前記音発生装置の故障の有無を判断する故障判断手段36と、を有する【選択図】図1
